Answer:
is not a rectangle
Step-by-step explanation:
The midpoints of the diagonals are ...
AC midpoint = ((2, -2) +(11, 13))/2 = (13/2, 11/2)
BD midpoint = ((14, 10) +(-2, 1))/2 = (6, 11/2)
The midpoints of the diagonals are different, so this is not a rectangle or any sort of parallelogram.
Answer:
Step-by-step explanation:
Hi there!
Length of the field:
units
Width of the field:
units
To find how much greater the length of the field is than the width, subtract the width from the length:

Open up the parentheses

Combine like terms

Therefore, the length is
units greater than the width.
I hope this helps!
Use pi•r^2 for the formula of a circle. filling it in, you get 3.14•64 which is 200.96
I believe it is zero, because there is no number less than 1.
A stuntman jumping off a 20-m-high building is modeled by the equation h = 20 – 5t2, where t is the time in seconds. A high-speed camera is ready to film him between 15 m and 10 m above the ground. For which interval of time should the camera film him?
Answer:

Step-by-step explanation:
Given:
A stuntman jumping off a 20-m-high building is modeled by the equation
-----------(1)
A high-speed camera is ready to making film between 15 m and 10 m above the ground
when the stuntman is 15m above the ground.
height
Put height value in equation 1





We know that the time is always positive, therefore 
when the stuntman is 10m above the ground.
height
Put height value in equation 1







Therefore ,time interval of camera film him is
